Built for the water

A logbook that fills itself.

Explore Riffle the way a trip unfolds. Tap a moment.

Plan the trip. Match the hatch. Pick the rig. Walk to the water already ahead.

Hatchdex and hatch calendar

See what's emerging right now where you fish. Mayflies, caddis, stones, midges, and more. Six insect orders with seasonal windows that update as you log them.

Plan trips and save spots

Pin productive water as you find it. Plan trips ahead, drop spots on the map, and return to them with the route already plotted.

Rigs and gear locker

Save your go-to rigs for fly, spin, and surf, and set an active rig per water type. Your gear locker travels with you.

No menus. No typing. Cold-hand and wet-glove friendly. Riffle gets out of the way so you can fish.

Background GPS tracking

Start a trip, lock your phone, and fish. Riffle records your exact route in the background all day. Every pool, every run, every wade, mapped without touching your phone.

Two-tap catch logging

Species chip, then checkmark. Done. Designed for cold, wet hands. One-handed, no typing required. Add size, lure, photo, and depth when you want, skip it when you don't.

Live Activity and lock screen widget

During an active trip, your lock screen and Dynamic Island show your catch count, distance, and time on the water. Glance, don't unlock.

Works without signal

Built for remote rivers and mountain streams. Riffle saves everything locally and syncs when you're back in range. No cell service, no problem.

End the trip and the story writes itself. Route, catches, weather, and milestones, all stitched together.

Trip review with catches pinned

See your full route with every catch dropped where it happened. Photos, lures, and notes alongside the map. Re-walk the trip without leaving the truck.

Weather at every catch

Pressure, temperature, wind, cloud cover, and humidity charted across the whole trip with each catch marked. Finally see what was actually working.

Fish-dex across 203 species

Nine groups, 203 species. See what you've caught, what you haven't, and your personal best for each one. Your logbook becomes a living record of every species you've ever landed.

Milestones, PBs, and stats

First of a species. Personal best. Biggest fish in a new state. Riffle calls them out automatically. Lifetime, monthly, and day-by-day stats fall out for free.

Logbook search

One search across catches, trips, planned trips, species, and insects. Find that brown trout from October without scrolling.

Photo scan and import

Backfill trips you never logged. Scan your camera roll and Riffle pulls the dates, GPS, and photos to reconstruct old days on the water.

How it works

Three taps. Then fish.

No setup. No manual entry. No friction between you and the water.

Start your trip

One tap and Riffle starts recording your GPS route in the background. Lock your screen and go fish. It runs all day without draining your battery.

Log catches as they happen

Tap a species chip, hit the checkmark. Done in two taps with one hand. Add size, lure, depth, or a photo if you want, or keep moving.

Review at the truck

End the trip and see your full route, every catch pinned to where it happened, your stats, and your photos. All in one place.
